Since 1994 ends in 4, it is divisible by 2.
So 1994 = 2*997.
Now 997 is prime.
How do we tell?
If we compute the nearest exact square root
of 997 we get 31 because 31² = 961 and 32² = 1024.
So we must divide 997 by all the prime numbers
less than or equal to 31. Since none of these divide 997
evenly, 997 is prime.
So the answer to your question is 2*997.
